That's me! I use parental controls to try and protect my elderly father on other platforms (he's always quick to fall for ads and download Android apps he doesn't need). Unfortunately Facebook doesn't allow you to enable parental controls on an adult, and they also pretty severely limit your ability to update your birthday! Which is unfortunate because Facebook is such a hostile platform.
I started a company a few months ago that is trying to help people like you do exactly this! I would love to chat with you to hear what has worked, what hasn't, what product features you would be most excited about. If you'd be willing to chat, please email me kevin at trylifeguard.com
